    Abstract
    In the development and design of parachutes, select data parameters are required for evaluation. These parameters give the designer dynamic information in actual environments providing stress, load, and glide ratio information. At present this information (altitude, rate of descent, total velocity, acceleration, dynamic pressure and attitude), is obtained by the use of space positioning methods. Meterological data, used to calculate some of these parameters, are obtained from rawinsonde balloons which are launched one half to two hours before and after the drop test. Typical combined data accuracies are on the order of plus or minus f ive percent with most of these errors being ascribed to the fact that the weather data is not taken at the time of the test and atmospheric conditions change rather quickly during the morning hours when the tests are typically done. A method has been developed which will measure meterological data real time. Direct measurements are taken via transducers ie. pressure, acceleration, attitude, temperature and humidity. These transducers are combined in the microprocessor circuitry to obtain final data prior to solid state recording or transmission. This paper will describe the methods and justifications for pursuing a different type of data gathering system.

    The export option will allow you to export the current search results of the entered query to a file. Different formats are available for download. To export the items, click on the button corresponding with the preferred download format.

    By default, clicking on the export buttons will result in a download of the allowed maximum amount of items.

    To select a subset of the search results, click "Selective Export" button and make a selection of the items you want to export. The amount of items that can be exported at once is similarly restricted as the full export.

    After making a selection, click one of the export format buttons. The amount of items that will be exported is indicated in the bubble next to export format.
